all of task has gone swapping out.

current namespace which isn't always what we want.
The main use for this is to make it easier to handle crashes that happened
within a container.

This is not the correct way to submit a change to stable.

Currently, trace-cmd outputs data of saved_cmdlines to a trace.dat file

Hi Steven,
This patch series extracts the trace_clock file for switching outputting format
of timestamp. This patch series uses the options feature, so trace-cmd keeps
backward compatibility.
In tsc or counter modes, trace-cmd should output timestamp not in the sec.usec
format but in the raw

The perf LBR code has special code to filter specific
instructions in software.
The LBR logs any instruction address, even if IP just faulted.
This means user space can control any address by just branching
to a bad address.

Because the modules' symbole (CONFIG_MODULES) may not yet be set when
we check a symbol's tristate capabilty, we'll always find that tristate
symbols are booleans, even if we randomly decided that to enable modules:

From: "Yann E. MORIN"
For randconfig, if a list of required symbols is specified with
KCONFIG_ALLCONFIG, such symbols do not "have a value" as per
sym_has_value(), but have the "valid" flag set.
